Abstract
Provided is a door mirror of automobile. The mirror comprises a frame fitted with a piece of glass, a bracket mounted on a body of the automobile and shaped to matingly couple to the frame, and a gear mechanism disposed in the connecting portions of both the frame and the bracket. A clockwise or counterclockwise turning of the frame about a pivot of the gear mechanism causes meshed gearwheels of the gear mechanism to rotate the same, thereby adjusting an angle of the frame about the bracket in a smooth, precise way.
Description
- The present invention relates to door mirrors of automobiles and more particularly to an improved door mirror of an automobile.
- A variety of door mirrors of an automobile have been available. However, none of them are interchangeable as far as the present inventor is aware. Moreover, many types of door mirror are relatively complex in constructions, costly to manufacture, trouble-prone, and unreliable in use. Thus, the need for improvement still exists.
- It is an object of the present invention to provide a door mirror mounted on an automobile, comprising a frame fitted with a piece of glass and comprising upper and lower first attachment members extended toward a body of the automobile, either first attachment member including a recess in its bottom or top, a circular cavity on the recess, and a vertical hole through the cavity to be in communication with the top and the bottom; two resilient members each disposed in a shoulder of the hole; a bracket mounted on the body of the automobile and comprising upper and lower second attachment members being shaped to matingly couple to the lower and upper first attachment members respectively wherein the upper second attachment member comprises a top circular cavity and the lower second attachment member comprises a bottom circular cavity; two pairs of gearwheels wherein each gearwheel comprises a central aperture and an annular toothed section formed on one surface around the aperture, the upper first and second attachment members one gearwheel of one pair is disposed in the cavity of the upper first attachment member with its toothed section being flush with the recess of the upper first attachment member, the other gearwheel of one pair is rested upon the top circular cavity of the upper second attachment member with its toothed section being flush with a top of the upper second attachment member, one gearwheel of the other pair is disposed in the cavity of the lower first attachment member with its toothed section being flush with the recess of the lower first attachment member, the other gearwheel of the other pair is rested upon the bottom circular cavity of the lower second attachment member with its toothed section being flush with a bottom of the lower second attachment member such that each pair of gearwheels are meshed together, and the aperture of each gearwheel in the circular cavity of either second attachment member has internal threads; and two screws each having an outer threaded section at its end portion, the threaded section being adapted to secure to the threads of the aperture when the screw is driven through the resilient member, the hole, and the aperture of one gearwheel of one pair into the aperture of the other gearwheel of one pair, wherein a clockwise or counterclockwise turning of the frame about the screws causes the gearwheels disposed in the first attachment members to rotate clockwise or counterclockwise relative to the gearwheels in the second attachment members.
- The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
-
FIG. 1 is an exploded view of a preferred embodiment of door mirror of automobile according to the invention; -
FIG. 2 is a front plan view in part section of the assembled door mirror; -
FIG. 3 is a perspective view of the door mirror; and -
FIG. 4 is a top plan view of two door mirrors mounted on an automobile with one of them being shown in detail for illustrating a pivoting of the door mirror. - Referring to FIGS. 1 to 4, there is shown a door mirror mountable in an automobile in accordance with a preferred embodiment of the invention. The door mirror comprises a
frame 1 and abracket 2. Each component will be described in detailed below. - The
frame 1 is fitted with a piece of glass and comprises upper and lowerfirst attachment members 11 extended toward the body of an automobile. Eachfirst attachment member 11 is a flat member and comprises arecess 12 in its bottom or top, a circular cavity 14 on therecess 12, and avertical hole 13 through the cavity 14 to be in communication with the top and the bottom. Twocompression springs 4 each is rested upon a shoulder in thehole 13. A gear assembly is provided and comprises a pair ofgearwheels 3. Thegearwheel 3 comprises acentral aperture 32 and an annular,toothed section 31 formed on one surface around theaperture 32. - The
bracket 2 is mounted on the body of the automobile and comprises upper and lowersecond attachment members 21 being shaped to matingly couple to the lower and upperfirst attachment members 11 respectively. - For the upper first and
second attachment members gearwheel 3 is disposed in the cavity 14 with itstoothed section 31 being flush with therecess 12, and theother gearwheel 3 is rested upon a top circular cavity 22 of thesecond attachment member 21 with itstoothed section 31 being flush with the top of thesecond attachment member 21. - For the lower first and
second attachment members gearwheel 3 is disposed in the cavity 14 with itstoothed section 31 being flush with therecess 12, and theother gearwheel 3 is rested upon a bottom circular cavity 22 of thesecond attachment member 21 with itstoothed section 31 being flush with the bottom of thesecond attachment member 21. - Also, the
central aperture 32 of theother gearwheel 3 in the circular cavity 22 of thesecond attachment member 21 is formed as a threaded one so as to threadedly secure to an end portion of the shank of eitherscrew 5 driven through thespring 4, thehole 13, and thecentral aperture 32 of onegearwheel 3 into thecentral aperture 32 of theother gearwheel 3. In this position (seeFIG. 3 ), each pair ofgearwheels 3 are meshed together. - As shown in
FIG. 4 , for retracting the door mirror toward the body of the automobile, a driver may counterclockwise turn theframe 1 about a pivot (i.e., the screws 5) with thegearwheels 3 disposed in thefirst attachment members 11 of theframe 1 being smoothly rotated relative to thegearwheels 3 disposed in thesecond attachment members 21 of thebracket 2. The extending of the door mirror relative to the body of the automobile is a simple reverse operation of the above. Thus, it will not be described in detail. In view of the above, it is seen that an angle of theframe 1 about thebracket 2 can be adjusted smoothly and precisely. - While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
